I also use it to water plants. I am not sure hopefully someone will post if I am wrong. But I thought the exit water does have some containments in it. Like maybe a higher concentration than what originally enters. I thought I read it is like a self purge. Probably potable but I would not drink it

I donno what you mean by reintroduce back into your water supply? But I as well hated the fact that you are supposed to hook it up to your drain and waste it, so I didnt hook mine up to a drain I just drain it into a bucket and wash my laundry with it... Works great

If you are talking about running the waste line off the ro unti and run it back into your water main. Not sure if that could work because of the pressure in the water supply.

You can run the waste water through another ro membrane look at bulk reef supply they have a kit to do that

You can drink RO waste water.

Because we have backflow preventers you would only be able to put it back into your local plumbing and that would require a pump that could overcome the back pressure of your house pressure. The other good uses above are great and I'm shure there are many more.

There are RO systems called Zero Waste. Costco was selling one a while back. They use a pump (as mentioned above) to return the water to the hot water side of your plumbing. As long as the GPD is low, it will not be a problem (feed back).

Btw, my waste water runs into my FW tanks sump for auto water changes (kills two birds with one stone).

you could always use a holding tank and plum it to sinks for washing hands, toilets for flushing as stated before esp washing clothes plumbed into the washer. fig savings on water. If you own a house with no septic tank concider getting a gas station tank buried in your back yard. you can run your down spouts and ro into it. capture rain water and ro water to run your whole house. yea i'm nuts but it can be done.

Ciclids love it. A pump increases the effeciency. As much as 1:1 ratio. As far as re-filtering it. That would be hard to do. A plumber might be able to re-link it to your house. A lot of people use it for laundry or pond top off. I know how you feel. Water here can be as much as 65cents per gallon. I buy it from the lfs for 63cents so I save a little.

Ive been thinking about running the waste tubing out to the garden and then attaching it to a soaker hose which would be laced around the garden.

I hooked up the waste water to a soaker hose around the garden today and it works great. It just evaporated real fast in the peak of the day sun here in Florida. I'll have to run it at night
